Possibility of conjunction between altruism and egoism

Both altruism and egoism are two types of motivations for action. An altruistic action is performed to benefit the other, whereas egoistic action is performed to benefit oneself. The strict definition of altruism states that an action ceases to be altruistic if the actor receives the benefit of his action as a consequence directly or indirectly. On the other hand, egoism particularly psychological egoism presupposes that all actions, whether performed for oneself or the other, are always self-interested in nature and hence, egoistic. Given the dichotomous existence between the two types of actions, which on many occasions create conceptual misapprehension, a different alternative will be explored. The new inquiry will throw light on the possibility that we commit some kind of motivational extremism on a conceptual level. It will further be argued that altruism and egoism may have one singular motivational source through which various actions emerge.
